About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX750-10S
The AirTAC SAIJ80X750-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 2513N of push force and 2268N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The integrated -10 adjustment mechanism allows you to fine-tune the end-of-stroke position within a 740-750mm usable travel window during commissioning.
This unit includes a SUS304 stainless steel rod (code B) and PT tapered port threads for robust fluid connectivity. Equipped with a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The rear screw acts purely as a mechanical stop for position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX750-10S Is Used
Precision End-Stop Tuning
Dial in the exact 740-750mm travel distance during machine commissioning to accommodate varying product dimensions without external stopper hardware.
Heavy-Duty Diverting
Provides 2513N of push force at 0.5 MPa to reliably divert heavy pallets or workpieces along high-throughput conveyor lines.
Automated Assembly Presses
Applies consistent clamping pressure in automated stations, utilizing the 30-800 mm/s speed range and dual air cushions for smooth operation.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX750-10S the Right Cylinder?
Choose this 80mm bore cylinder when an application requires substantial thrust—such as the 2513N push force at 0.5 MPa—exceeding the 982N capacity of a 50mm bore, but without stepping up to the larger 100mm bore that offers 3927N. The adjustable stroke is ideal for machine setups requiring precise end-stop tuning without adding external physical stops or swapping out the entire cylinder body.
Because this model features a 750mm stroke, which exceeds 300mm, an external guide rail is strongly recommended to prevent excessive side-loading on the rod. For applications requiring true load-holding in the event of air pressure loss, note that this cylinder's adjuster is not a lock; consider the AirTAC SAIL or BSAI series instead. This SAIJ variant supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80BX750-10S FAQ
At an operating pressure of 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the maximum rated pressure of 1.0 MPa, it delivers up to 513 kgf.
The nominal stroke is 750mm, and the -10 adjustment code allows you to shorten the effective stroke by up to 10mm. This creates a usable travel window of 740-750mm for fine-tuning the retract end position.
